Answer:
Given: If y varies jointly as x and z, and y = 36 when x =3 and z= 4, find z when y = 36 and x = 4.
Step 1: Write the correct equation. Joint variation problems are solved using the equation y = kxz.
Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when y = 36 when x =3 and z = 4.
Therefore, the constant of variation k is 3.
Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2.
Step 4: Use the equation found in step 3 and the remaining information given in the problem to answer; in this case, you need to find z when y = 36 and x = 4.
